背景技术
有机发光二极管(OLED)显示面板具有广色域，厚度薄、较高的对比度、可弯曲、省电等优点。目前，OLED的像素层是通过有机材料经高精细金属掩膜板(Fine Metal Mask，FMM)真空蒸镀而成，在蒸镀过程中，在磁隔板的作用下，将基板与高精度金属掩膜板贴近，随后在基板的不同位置上分别蒸镀不同的EL材料。
然而，由于长条形的高精细金属掩膜板本身具有较大的流动性，且蒸镀过程中会受到磁力、静电、EL材料积累等因素的影响，易发生偏移，以导致FMM损伤、混色等不良现象，严重限制了FMM的应用，同时导致OLED显示面板产品良率较低。

下面，参考附图描述根据本申请第一方面实施例的OLED显示面板100。
如图1和图2所示，OLED显示面板100包括基板1和像素层2，像素层2设在基板1的厚度方向(例如，图2中的CC’方向)的一侧，且像素层2包括多组像素单元组21，多组像素单元组21沿第一方向(例如，图1中的AA’方向)依次设置，每组像素单元组21包括多个沿第二方向(例如，图1中的BB’方向)排布的像素单元211，第二方向与第一方向垂直，像素单元211包括第一子像素211a、第二子像素211b和第三子像素211c；例如，在图1、图4-图7的示例中，第一子像素211a为红色子像素，第二子像素211b为绿色子像素，第三子像素211c为蓝色子像素，但不限于此。其中，像素层2的第三子像素211c可以通过使用掩膜板101蒸镀形成。
在本申请的描述中，“多个”、“多组”的含义均是两个或两个以上。
如图1和图2所示，OLED显示面板100还包括间隔支撑层3，间隔支撑层3与像素层2均设在基板1的厚度方向的同侧，且间隔支撑层3和像素层2均设在基板1的表面上，间隔支撑层3包括多组支撑块组31，多组支撑块组31沿第一方向依次设置，每个支撑块组31包括多个沿第二方向排布的支撑块311，支撑块311可以与第一子像素211a、第二子像素211b和第三子像素211c分别间隔设置，便于合理利用第一子像素211a、第二子像素211b和第三子像素211c中其中两个之间的间隔，提升支撑块311布置的灵活性，同时在保证支撑块311具有足够支撑面积的前提下，有利于节省支撑块组31的用材量，降低成本。在使用掩膜板101(mask)蒸镀形成像素层2的第三子像素211c时，由于支撑块311的厚度大于第三子像素211c的厚度，且支撑块311适于支撑在基板1和掩膜板101之间，则支撑块311可以将基板1和掩膜板101隔离，支撑块311可以起到支撑掩膜板101的作用，避免因掩膜板101易直接贴于基板1表面而易发生掩膜板101损失(例如FMM损失)、产生Part ical(粒子)，减少静电的产生，从而避免蒸镀混色、错位等异常。
其中，每组像素单元组21的多个第三子像素211c适于与掩膜板101的一个开口101a对应，开口101a沿第二方向延伸成长条形，则掩膜板101上可以形成有多个开口101a，多个开口101a可以沿第一方向依次间隔设置，每组像素单元组21的多个第三子 像素211c可以形成像素区域，该像素区域可以通过同一个开口101a蒸镀，有利于增加mask的开口101a面积，降低蒸镀难度。
其中，“长条形”可以理解为开口101a在第二方向上的长度大于开口101a在第一方向上的宽度，例如长条形可以为长圆形、或矩形等。
如图1、图4-图7所示，每组像素单元组21的第三子像素211c在第一方向上的至少一侧设有支撑块组31，即每组像素单元组21的第三子像素211c在第一方向上的其中一侧设有支撑块组31，或者每组像素单元组21的第三子像素211c在第一方向上的两侧分别设有支撑块组31，或者多组像素单元组21中的至少一组的第三子像素211c在第一方向上的其中一侧设有支撑块组31、且多组像素单元组21中的至少一组的第三子像素211c在第一方向上的两侧分别设有支撑块组31；则在蒸镀时，掩膜板101上每个开口101a在第一方向上的至少一侧支撑有支撑块组31，即掩膜板101上每个开口101a在第一方向上的其中一侧支撑有支撑块组31，或者每个开口101a在第一方向上的两侧分别支撑有支撑块组31，或者多个开口101a中的至少一个在第一方向上的其中一侧支撑有支撑块组31、且多个开口101a中的至少一个在第一方向上的两侧分别支撑有支撑块组31。由此，使得支撑块组31与开口101a错位设置，从而支撑块组31可以更好地支撑mask，保证间隔支撑层3对掩膜板101的稳定支撑，避免掩膜板101发生偏移，减少因掩膜板101流动性而产生混色，有效减少了mura等不良的产生，提高了产品良率。
其中，多组像素单元组21中任意两组并未共用支撑块组31，则每组像素单元组21对应至少一组支撑块组31。
相对于一些技术中，每组像素单元组21的多个第三子像素211c与掩膜板101的一个开口101a对应，使用掩膜板101蒸镀形成第三子像素211c时，将支撑块组31与像素单元组21齐平设置，支撑块组31的每个支撑块311设在相邻的两个第三子像素211c之间，使得支撑块311对应于开口101a设置，每个支撑块311需要同时支撑开口101a的宽度两侧，此时支撑块311易出现无法正常支撑mask缺陷，导致蒸镀无法正常进行。本申请中，通过在每组像素单元组21的第三子像素211c在第一方向上的至少一侧设有支撑块组31，使得支撑块组31与掩膜板101的开口101a错位设置，从而支撑块组31可以更好地支撑mask，保证蒸镀正常进行，同时有效减少了mura等不良的产生，提高了产品良率。
如图1和图3所示，掩膜板101可以为FMM，FMM可以为Slit形状，即Slit FMM。基板1可选为玻璃基板。
可以理解的是，支撑块组31的支撑块311的数量与对应像素单元组21的像素单元211的数量、以及支撑块组31的支撑块311在第二方向上的布置可以根据实际应用具体设置。例如，在第二方向上，支撑块组31的多个支撑块311与像素单元组21的多个像素单元211依次交替设置(如图1、图4-图7所示)；或者，在第二方向上，每个像素单元211的第一子像素211a和第二子像素211b之间分别设有一个支撑块311；或者，在第二方向上，支撑块311与对应像素单元211的第一子像素211a、或第二子像素211b、或第三子像素211c中的其中一个齐平设置，比如在第二方向上，支撑块311与对应像素单元211的第一子像素211a齐平设置，则支撑块311和对应像素单元211的第一子像素211a可以位于沿第一方向延伸的直线上；但不限于此。
在一些实施例中，如图5和图6所示，每组像素单元组21的第三子像素211c在第一方向上的两侧分别设有支撑块组31，使得支撑块组31的布置密度较大，进一步提升了间隔支撑层3对掩膜板101的支撑效果，避免因掩膜板101流动性较大而在静电的作用下直接贴于基板1表面，进一步有效避免了掩膜板101损失、产生Part ical、混色等不良现象，从而有利于进一步提高产品良率。
在图5和图6的示例中，每组像素单元组21的第三子像素211c在第一方向上的两侧分别设有支撑块组31，相邻两组像素单元组21的第三子像素211c并未共用支撑块组31。
当然，本申请不限于此；在另一些实施例中，如图1、图4和图7所示，每组像素单元组21的第三子像素211c在第一方向上的其中一侧设有支撑块组31，从而在保证产品良率的前提下，减少支撑块组31的布置数量，有利于简化OLED显示面板100的结构。
在图1、图4和图7的示例中，每组像素单元组21的第三子像素211c在第一方向上的其中一侧设有支撑块组31，且每组支撑块组31分别位于对应像素单元组21的第三子像素211c的同侧。
在一些实施例中，如图1、图4-图7所示，像素单元组21的多个第一子像素211a和多个第二子像素211b沿第一基准线L1依次交替设置，则在第一基准线L1的延伸方向上，像素单元组21的相邻两个第一子像素211a之间设有一个第二子像素211b、相邻两个第二子像素211b之间设有一个第一子像素211a；像素单元组21的多个第三子像素211c沿第二基准线L2依次设置，第二基准线L2和第一基准线L1平行设置且第二基准线L2和第一基准线L1均沿第二方向延伸。由此，OLED显示面板100的第一子像素211a、第二子像素211b和第三子像素211c的排布可以形成为Sl it像素排布，可以 延长OLED显示面板100的使用寿命，从而提高了产品的核心竞争力；例如，Slit像素排布可延长OLED显示面板100的寿命高达40％以上。
在一些实施例中，如图1、图4-图7所示，在第一方向上，多条第一基准线L1和多条第二基准线L2依次交替设置，则在第一方向上，相邻两条第一基准线L1之间设有一条第二基准线L2，相邻两条第二基准线L2之间设有一条第一基准线L1，从而保证OLED显示面板100的第一子像素211a、第二子像素211b和第三子像素211c的排布可以形成为Slit像素排布，保证使用寿命。
在图1、图4-图7的示例中，第一子像素211a为红色子像素，第二子像素211b为绿色子像素，第三子像素211c为蓝色子像素，则像素单元组21的多个红色子像素和绿色子像素沿第一基准线L1依次交替设置，像素单元组21的多个蓝色子像素沿第二基准线L2依次设置，第二基准线L2和第一基准线L1沿第一方向间隔设置，第二基准线L2和第一基准线L1均形成为直线，且在第二方向上，像素单元211的蓝色子像素位于该像素单元211的红色子像素和绿色子像素之间。
在一些实施例中，如图1所示，在第一方向上，支撑块组31设在对应像素单元组21的第一基准线L1和第二基准线L2之间，则在第一方向上，支撑块组31的支撑块311的中心位于对应像素单元组21的第一基准线L1和第二基准线L2之间，此时支撑块组31的布置可以为：每组像素单元组21的第三子像素211c在第一方向上的其中一侧设有支撑块组31，支撑块311可以稳定支撑在掩膜板101实材区，以保证间隔支撑层3对掩膜板101的支撑效果，减少掩膜板101发生的在第一方向上的偏移，从而减少因掩膜板101流动性导致的混色，保证产品良率。
可以理解的是，当支撑块组31在第一方向上位于对应像素单元组21的第一基准线L1和第二基准线L2之间时，支撑块组31的支撑块311的数量与对应像素单元组21的像素单元211的数量、以及支撑块组31的支撑块311在第二方向上的布置可以根据实际应用具体设置。例如，在第二方向上，支撑块组31的多个支撑块311与像素单元组21的多个像素单元211依次交替设置(如图1所示)；或者，在第二方向上，每个像素单元211的第一子像素211a和第二子像素211b之间分别设有至少一个支撑块311；或者，在第二方向上，支撑块311与对应像素单元211的第一子像素211a、或第二子像素211b、或第三子像素211c中的其中一个齐平设置。
在一些实施例中，如图4所示，在第一方向上，支撑块组31设在相邻两个像素单元组21之间，则在第一方向上，支撑块组31的支撑块311的中心位于相邻两个像素单元211之间，此时支撑块组31的布置可以为：每组像素单元组21的第三子像素211c 在第一方向上的其中一侧设有支撑块组31，或者，多组像素单元组21中的至少一组的第三子像素211c在第一方向上的其中一侧设有支撑块组31、且多组像素单元组21中的至少一组(例如，位于显示面板边缘处的像素单元组21)的第三子像素211c在第一方向上的两侧分别设有支撑块组31，以保证间隔支撑层3对掩膜板101的支撑效果，保证产品良率。
可以理解的是，当支撑块组31在第一方向上位于相邻两个像素单元组21之间时，支撑块组31的支撑块311的数量与对应像素单元组21的像素单元211的数量、以及支撑块组31的支撑块311在第二方向上的布置可以根据实际应用具体设置。例如，在第二方向上，支撑块组31的多个支撑块311与像素单元组21的多个像素单元211依次交替设置(如图4所示)；或者，在第二方向上，每个像素单元211的第一子像素211a和第二子像素211b之间分别设有至少一个支撑块311；或者，在第二方向上，支撑块311与对应像素单元211的第一子像素211a、或第二子像素211b、或第三子像素211c中的其中一个齐平设置。
在一些实施例中，如图7所示，在第一方向上，支撑块组31的多个支撑块31的中心均位于第一基准线L1上，保证支撑块31对掩膜板101的支撑效果。
在一些实施例中，如图5和图6所示，在第一方向上，每组像素单元组21的第一基准线L1和第二基准线L2之间分别设有支撑块组31，且在第一方向上，每相邻两个像素单元组21之间分别设有支撑块组31，此时支撑块组31的布置可以为：每组像素单元组21的第三子像素211c在第一方向上的两侧分别设有支撑块组31，以进一步有效提升间隔支撑层3对掩膜板101的支撑效果，避免掩膜板101因流动性而在磁力、静电以及EL材料累计等作用下直接贴于基板1表面，从而减少了不良现象，保证了产品良率。
可以理解的是，当像素单元组21的第三子像素211c在第一方向上的两侧分别设有支撑块组31时，这两侧支撑块组31的支撑块311的数量以及支撑块311在第二方向上的布置可以根据实际应用具体设置，则第三子像素211c在第一方向上两侧的支撑块组31的布置可以相同、也可以不同。
在一些实施例中，如图5所示，位于像素单元组21在第一方向上两侧的两个支撑块组31分别为第一支撑块组31a和第二支撑块组31b，第一支撑块组31a的每个支撑块311与第二支撑块组31b的对应支撑块311在第二方向上分别齐平设置，则第一支撑块组31a的每个支撑块311与第二支撑块组31b的对应支撑开可以位于沿第一方向延伸的直线上，此时，第一支撑块组31a的支撑块311的数量与第二支撑块组31b的支撑块 311的数量可以相等，使得第一支撑块组31a的多个支撑块311的布置方式与第二支撑块组31b的多个支撑块311的布置方式相同，有利于简化支撑块311的布置方式，使得支撑块311布置较为规整，方便支撑块组31的加工。
在一些实施例中，如图6所示，位于像素单元组21在第一方向上两侧的两个支撑块组31分别为第一支撑块组31a和第二支撑块组31b，第一支撑块组31a的每个支撑块311与第二支撑块组31b的每个支撑块311在第二方向上分别错开设置，此时第一支撑块组31a的多个支撑块311的布置方式与第二支撑块组31b的多个支撑块311的布置方式不同，且第一支撑块组31a的支撑块311的数量与第二支撑块组31b的支撑块311的数量相等或不等，从而在保证间隔支撑层3的支撑作用下，有利于减少支撑块311的数量，简化OLED显示面板100的结构，降低成本。
例如，在图6的示例中，在第二方向上，第一支撑块组31a的每个支撑块311分别位于第二支撑块组31b的相邻两个支撑块311之间，第二支撑块组31d的每个支撑块311分别位于第一支撑块组31a的相邻两个支撑块311之间，同样可以使得支撑块311布置较为规整。
当然，第一支撑块组31a的多个支撑块311的布置方式和第二支撑块组31b的多个支撑块311的布置方向不限于此；例如，第一支撑块组31a的支撑块311的数量小于第二支撑块组31b的支撑块311的数量，且第一支撑块组31a的每个支撑块311与第二支撑块组31b的一部分支撑块311在第二方向上分别齐平设置，第二支撑块31b其余部分的支撑块311与第一支撑块组31a的支撑块311在第二方向上均错开设置。
在一些实施例中，如图1、图4-图7所示，每个像素单元211分别对应至少一个支撑块311设置，使得支撑块311具有合适的布置密度，以保证间隔支撑层3对掩膜板101的支撑效果。
例如，如图1、图4-图7所示，在第二方向上，像素单元组21的多个像素单元211和支撑块组31的多个支撑块311依次交替设置，以合理利用相邻像素单元211之间的间隔，便于支撑块311的设置。又例如，在第二方向上，每个像素单元211的第一子像素211a和第二子像素211b之间分别设有一个支撑块311，以合理利用第一子像素211a和第二子像素211b之间的间隔，便于支撑块311的设置。
在一些实施例中，支撑块311的横截面积沿朝向靠近基板1的方向逐渐减小，使得支撑块311的远离基板1的一端的横截面积较大，便于保证支撑块311与掩膜板101之间具有较大的接触面积，保证支撑块311对掩膜板101的支撑作用，使得间隔支撑层3有效支撑掩膜板101，减少混色、错位等不良现象。其中，支撑块311的横截面可以 与基板1的厚度一侧的表面平行。
例如，支撑块311沿第一方向的正投影和支撑块311沿第二方向的正投影中的至少一个形成为梯形，而由于支撑块311的横截面积沿朝向靠近基板1的方向逐渐减小，则支撑块311沿第一方向的正投影和支撑块311沿第二方向的正投影中的至少一个可以形成为倒梯形，则支撑块311结构简单、加工方便。
根据本申请第二方面实施例的显示装置，包括根据本申请上述第一方面实施例的OLED显示面板100。例如，显示装置还可以包括壳体，OLED显示面板100设于壳体。
